Alibaba’s Qwen AI models enable low-cost DeepSeek alternatives from Stanford, Berkeley

The race to produce the cheapest top-performing artificial intelligence (AI) model is heating up with a new reasoning model from US computer scientists, including renowned Chinese-American “AI godmother” Li Feifei, that was trained for under US$50 on the back of Alibaba Group Holding’s open-source technology, following the breakthrough success of China’s DeepSeek.
The S1 reasoning model was developed on top of the Chinese e-commerce giant’s Qwen2.5-32b-Instruct model by researchers from Stanford University, where Li works, and the University of Washington, according to a research paper published last week.
The capabilities of Alibaba’s model are fresh evidence of how China is narrowing the AI gap with leading US players, following DeepSeek’s release of low-cost, high-performance open-source models that captured global attention. Hong Kong-listed shares of Alibaba, owner of South China Morning Post, gained 6 per cent on Monday.
After being trained with answers to 1,000 carefully curated questions and the “thinking process” distilled from Google’s Gemini Thinking Experimental model, the S1 model outperformed OpenAI’s o1-preview on maths and programming skills, according to the paper.
The cost of running just the graphics processing units (GPUs) to develop S1 could be as low as US$14 based on the compute noted in the research, which says the model was trained for 26 minutes on 16 Nvidia H100s. These chips can be rented for US$2 per hour.
The key to training a powerful reasoning model at such a low cost – roughly the price of a sandwich at a New York deli – lies in the base model, according to Pan Jiayi, a computer scientist at the University of California, Berkeley. “Base model quality is the key,” he said.
